Description

The invention relates to a mechanical lock with an additional electronic module according to the features of the preamble of claim 1 and a method for locking and unlocking a mechanical lock with an additional electronic module according to the features of the preamble of claim 14.

From the WO 2013/114409 A1 A lock is known that can be adapted to specific circumstances. It is intended that individual extensions can be connected to the lock housing, which can include, for example, additional locking elements or drive devices and thus extend the lock housing. This makes it possible to individually upgrade the lock and adapt it to increased security requirements. However, the lock housing holder in the door must be designed to accommodate the enlarged lock housing. From the EP 3 299 552 A1 A motor lock with a drive module is known, which controls the entire lock mechanism via a slide plate for locking or unlocking.

Electronic additional modules are also known, which can be arranged outside the lock housing, whereby the additional module parts of the Locking mechanism in a lock is moved by an electronic drive of the additional module. This movement drives the locking mechanism and thus locks or unlocks the lock. The disadvantage of such additional modules is that the electronic drive usually affects the entire locking mechanism.

In practice, door openers are also used which are arranged in the frame of the door and work together with a mechanical lock to open or close electrically remote-controlled doors. An important criterion for such electrical door openers is the volume of the door opener and the holding force that can be achieved with the door opener. The disadvantage here is that a corresponding holder must be formed in the frame for the door opener.

The object of the present invention is to provide a mechanical lock with an additional electronic module which covers a wide range of applications and can be manufactured in a simple manner. A further object of the present invention is to eliminate the need for a separate door opener and replace it with a lock.

The object is achieved according to the invention by a mechanical lock with an additional electronic module according to the features of claim 1.

• wobei das Schloss ein Schlossgehäuse und eine darin angeordnete Schlossmechanik mit einer sperrbaren Schlossfalle aufweist und das Schloss ein von der Schlossmechanik bewegbaren Blockierelement aufweist, und
• wobei das Blockierelement durch die Schlossmechanik in eine Blockierstellung verlagerbar ist, in der das Blockierelement die Schlossfalle hintergreift und eine Bewegung der Schlossfalle blockiert ist, und wobei das Blockierelement durch die Schlossmechanik in eine Freigabestellung verlagerbar ist, in der die Schlossfalle verschwenkbar und translational verschiebbar ist, und
• wobei das elektronische Zusatzmodul im Schlossgehäuse angeordnet ist. Wesentlich dabei ist, dass das elektronische Zusatzmodul eine reine mechanische Öffnung der Tür verhindert, indem
• das elektronische Zusatzmodul ein schaltbares Verlagerungselement aufweist, welches eine Verlagerung des Blockierelements durch die Schlossmechanik verhindert oder erlaubt, und/oder
• dass das elektronische Zusatzmodul ein verlagerbares Elektronikmodul-Blockierelement aufweist, welches eine Verlagerung der Schlossfalle verhindert oder erlaubt.

According to the invention, a mechanical lock for a pivoting wing of a door or window with an additional electronic module is provided,

• wherein the lock has a lock housing and a lock mechanism arranged therein with a lockable lock latch and the lock has a blocking element movable by the lock mechanism, and
• wherein the blocking element can be displaced by the lock mechanism into a blocking position in which the blocking element engages behind the lock latch and a movement of the lock latch is blocked, and wherein the blocking element can be displaced by the lock mechanism into a release position in which the lock latch can be pivoted and translationally displaced, and
• The electronic additional module is located in the lock housing. It is important that the electronic additional module prevents a purely mechanical opening of the door by
• the additional electronic module has a switchable displacement element which prevents or allows displacement of the blocking element by the lock mechanism, and/or
• that the additional electronic module has a movable electronic module blocking element which prevents or allows the lock latch to be moved.

Furthermore, the object is achieved by a method for locking and unlocking a mechanical lock with an additional electronic module according to the features of claim 14.

According to the invention, a method for locking and unlocking a mechanical lock for a pivotably mounted leaf of a door or window with an additional electronic module is proposed, comprising locking or unlocking a lock latch by displacing a blocking element through a lock mechanism of the lock,
wherein the blocking element can be displaced by the lock mechanism into a blocking position in which the blocking element engages behind the lock latch and a movement of the lock latch is blocked, and wherein the blocking element can be displaced by the lock mechanism into a release position in which the lock latch is pivotable and translationally displaceable.

• indem das elektronische Zusatzmodul durch ein schaltbares Verlagerungselement eine Übertragung der Bewegung der Schlossmechanik auf das Blockierelement verhindert oder erlaubt, und/oder
• indem das elektronische Zusatzmodul durch ein verlagerbares Elektronikmodul-Blockierelement die Verlagerung der Schlossfalle verhindert oder erlaubt.

It is important that the additional electronic module prevents a purely mechanical opening of the door by the lock mechanism,

• by the additional electronic module preventing or allowing the movement of the lock mechanism to be transferred to the blocking element by means of a switchable displacement element, and/or
• The additional electronic module prevents or allows the lock latch to be moved using a movable electronic module blocking element.

The advantage of the device and method according to the invention is that the additional electronic module acts directly on blocking or releasing the lock latch and thus a purely mechanical opening of the door by the lock mechanism alone can be prevented via an electronic control. A further advantage is that the additional electronic module does not act on the entire lock mechanism.

A further advantage of the device according to the invention and the method according to the invention is that the functionality of the purely mechanical lock is expanded by the additional electronic module, whereby additional components such as a door opener can be replaced by the lock according to the invention with the additional electronic module and the method according to the invention. This means that it is no longer necessary to form an opening in the frame for the door opener. Another advantage is that by replacing the lock with the additional electronic module as a door opener, a much higher holding force is achieved compared to known door openers, since the latch interacts with a latch holder of a frame and not with moving parts of a door opener.

Another advantage is that the lock can be operated as a fully functional, purely mechanical lock without the additional module. The lock can be upgraded at any time, i.e. during manufacture of the lock, during assembly of the lock or at a later time, i.e. after assembly and commissioning of the lock.

A production kit comprising the lock and the additional electronic module can also be provided for sale. Alternatively, the additional electronic module can also be sold separately from the lock in order to subsequently upgrade an already installed lock with a corresponding additional electronic module.

By electronically blocking or releasing the lock latch using the additional electronic module, it is possible to use the lock according to the invention with the additional electronic module and the method according to the invention in escape doors and for escape door security.

When the door is locked, the lock latch is in its pre-locked position, with the blocking element engaging behind the lock latch in a blocking position so that the lock latch is fixed and cannot be pushed into the lock housing. When the door is unlocked, the blocking element is in a release position so that the lock latch can be pushed into the lock housing.

It can be provided that the additional electronic module has a motor as a drive, preferably an electric motor or a coil. It can be provided that the additional electronic module has a gear for transmitting a movement of the drive to the switchable displacement element or the electronic module blocking element.

It can be provided that the electronic module blocking element can be displaced by a drive of the electronic module into a blocking position in which the electronic module blocking element engages behind the lock latch and a movement of the lock latch is blocked, and wherein the electronic module blocking element can be displaced by the drive of the electronic module into a release position in which the lock latch can be pivoted and translationally displaced.

It can be provided that when the door is locked, the lock latch is in its pre-locked position, with the electronic module blocking element engaging behind the lock latch in a blocking position so that the lock latch is fixed and cannot be pushed into the lock housing. When the door is unlocked, the electronic module blocking element is in a release position so that the lock latch can be pushed into the lock housing.

It can be provided that the blocking element and/or the electronic module blocking element are designed as a linearly displaceable blocking slide and/or electronic module blocking slide or have a linearly displaceable blocking slide and/or electronic module blocking slide. It can be provided that the linearly displaceable blocking slide of the blocking element and/or the electronic module blocking slide causes the lock latch to be released or blocked.

The blocking element and/or the electronic module blocking element can also be designed as a rotatably mounted element which has a blocking section which can be optionally pivoted into or out of the movement range of the lock latch. It can be provided that the rotatably mounted element of the blocking slide and/or the electronic module blocking slide causes the lock latch to be released or blocked.

It can be provided that the blocking element and/or the electronic module blocking element is/are mounted perpendicular to the movement of the lock latch.

It can be provided that on the blocking element and/or the electronic module blocking element, preferably on the blocking slide and/or on the Electronic module blocking slide, two rollers each are rotatably mounted, the bearing axes of the two rollers being parallel to one another, and the two rollers contacting one another. It can be provided that the two rollers are each arranged on a blocking slide of the blocking element and/or the electronic module blocking element. It can be provided that in the blocking position the blocking slide engages behind the lock latch in such a way that one of the two rollers rests on the rear edge of the lock latch, the rollers assuming a dead center position in relation to the rear edge of the lock latch. This is possible in that the directions of movement of the lock latch and the blocking element and/or the electronic module blocking element are perpendicular to one another. The lock latch cannot therefore be moved by an external force acting on the lock latch, since the force is introduced into the two rollers in the dead center position.

The advantage is that the two rollers can absorb high forces in their dead center position. This makes it possible to provide a lock that has high resistance forces. Moving the two rollers out of the dead center position, on the other hand, causes the lock latch to be released safely. To move the two rollers out of the dead center position, for example, it is sufficient to move just one of the two rollers, preferably along the rear edge of the lock latch. The two rollers can also be moved out of engagement with the lock latch, or the two rollers can be tilted.

In particular, it can be provided that the blocking element and the electronic module blocking element are constructed in the same way with regard to the two rollers. The blocking element and the electronic module blocking element can both act on the rear edge of the lock latch. The lock latch can be blocked either only by the blocking element, or only by the electronic module blocking element, or simultaneously by the blocking element and the electronic module blocking element. Preferably, the lock latch is released when both blocking elements, i.e. the blocking element and the electronic module blocking element, release the lock latch.

It can be provided that the displacement element forms a switchable locking mechanism between the lock mechanism and the blocking element, wherein when the transmission of the movement is permitted, the locking mechanism is formed between the lock mechanism and the blocking element and when the transmission of the movement is prevented, the locking mechanism between the lock mechanism and the blocking element is released.

In an exemplary embodiment, it can be provided that the blocking element is urged towards the blocking position by a spring. In such an embodiment, the blocking element is in the blocking position by decoupling from the lock mechanism and can be transferred to the release position by the switchable displacement element by coupling it to the lock mechanism.

It can be provided that the displacement element is designed in such a way that when the transmission of the movement is permitted, the displacement of the blocking element is not compensated by the lock mechanism and when the transmission of the movement is prevented, the displacement of the blocking element is compensated by the lock mechanism, wherein the compensation is carried out by a movement of the displacement element in the electronic additional module. Such compensation can be carried out, for example, by a drive with a spindle and a spindle nut, in that the rotary movement of the drive is converted into a linear movement of the spindle nut in order to compensate for a linear movement of the lock mechanism for actuating the blocking element. It can be provided that the electronic additional module is equipped with a displacement element on the blocking element or on a movable component of the lock mechanism. With such an arrangement, the additional electronic module can compensate for a movement of the lock mechanism for activating the blocking element.

The lock latch can be designed as a tilt latch or as a cross latch or as a roller latch. A tilt latch is understood to be a lock latch with a latch head and a latch carrier, whereby the latch head is pivotably mounted on the latch carrier. A cross latch is understood to be a lock latch with a multi-part latch head and latch carrier, whereby the multiple parts of the latch head are pivotably mounted on the latch carrier according to an opening or closing direction of the door. A roller latch is understood to be a lock latch with a roller as the latch head, which is mounted on a latch carrier. The latch carrier of the respective lock latch is, for example, mounted in the lock housing so that it can move linearly. The latch head has an inlet slope and an outlet slope due to the respective design. A lock that is equipped with a tilt latch can be used on left-hinged doors as well as on right-hinged doors.

It can be provided that the lock has a locking element that can be actuated by the lock mechanism, and the locking element can be actuated by a slide plate of the lock mechanism between a pre-locked locking position and an unlocking position retracted into the lock housing.

It can be provided that the lock mechanism comprises a central slide plate, which serves to control the locking element and the blocking element. The locking of the locking element can be carried out via a guide rail arranged in the slide plate, which interacts with a pin of the locking element.

Furthermore, the lock mechanism can comprise a locking cylinder and/or a handle nut, as well as gear elements to transmit a movement of the locking cylinder or the handle nut to the locking element and/or the blocking element.

The lock may be provided with a handle for operating the lock mechanism via the handle nut.

The handle may be designed as a door handle or push bar.

It can be provided that the lock has a locking sensor which detects the position of the locking element, preferably the pre-locked locking position and/or the retracted unlocking position.

It can be provided that the locking element can be brought into the unlocking position and the blocking element can be brought into the release position by means of the handle. Such a function is provided for a door as an escape route security for use in escape and rescue routes. A lock with such a function is also called a panic lock. A panic lock has a locking element, a lock latch and a handle nut connected to a handle as well as a locking cylinder. When the panic lock is locked, i.e. when the bolt is in its pre-locked position and engages in a bolt receptacle in the door frame, the lock can only be opened manually by a user from the inside of the building by operating the handle. Turning the nut causes the locking element to be moved back into its closed position in the lock housing and the lock latch to be released. A key is not required for unlocking a panic lock from the inside of the building. A locking cylinder that can be turned with a key is used to lock the lock. As a rule, On the outside of the panic lock housing there is only a handle and a locking cylinder.

In order to provide a panic lock that has different panic functions, it can be provided that the handle nut is designed as a multi-part handle nut, i.e. has at least two nut parts and also one or more pawls for coupling and/or uncoupling the nut parts.

The lock housing can be designed as a built-in housing. It comprises a lock faceplate, a lock base and a removable lock cover.

It can be provided that the additional electronic module is arranged on the lock housing, preferably the lock base.

The mechanical mounts of the lock housing can, for example, be designed as form-fitting mounts into which the additional electronic module is inserted. Alternatively or additionally, the mechanical mounts can also be designed as screw connections or snap or clip connections. Riveting to accommodate and hold the additional electronic module is also possible in this sense.

One embodiment can provide that the lock has a control latch, a spring that acts on the control latch and at least one gear element that can be actuated by the control latch to connect the control latch to the lock mechanism, preferably to the slide. The control latch can be used to control the locking element and/or the lock latch, for example, in order to trigger a locking of the locking element in a self-locking lock as soon as the door is in the closed position. In addition, the control latch can have a sequence control that includes manipulation protection and Prevents the locking element from being excluded from the lock housing if the control latch is accidentally activated when the door is still open.

It can be provided that the additional electronic module is connected to a power supply line and/or control line.

The electronic additional module can be controlled by a door control unit or a door terminal that is spatially assigned to the door with the lock. The electronic additional module can also be controlled, i.e. additionally or alone, by a remote control unit. The remote control unit can be connected to the lock or the electronic additional module by cable or bus.

Fig.1 shows a door 3 which is arranged on hinges on a door frame 4. A lock 1 with a lock latch 11 is arranged in a lock receptacle of the door 3.

Fig.2 shows a first embodiment of the lock 1 according to the invention with an additional electronic module 2, wherein in this embodiment the additional electronic module 2 has a displaceable electronic module blocking element 12 and thereby prevents or allows the displacement of the lock latch 11.

The lock 1 has a lock housing 10 with a lock mechanism arranged therein and the lockable lock latch 11. The lock latch 11 is in the embodiment of the Fig.2 as a tilting latch 17, which is arranged pivotably on a latch carrier 15. The latch carrier 15 of the tilting latch 17 is mounted linearly movable in the lock housing 10. The direction of movement of the latch carrier 15 is the horizontal direction in the installed position of the lock 1, whereby the direction of movement of the latch carrier 15 and the tilting latch 17 mounted thereon is parallel to the direction of movement of a Fig.2 not shown locking element. The pivot axis of the tilt latch 17 runs parallel to the extension axis of a faceplate of the lock 1 and perpendicular to the direction of movement of the latch carrier 15. The latch carrier 15 is acted upon by a spring 16 supported on the lock housing 10, which urges the latch carrier 15 towards its extended position, as shown in Fig.2 shown.

A blocking element 12 which can be moved by the lock mechanism is arranged in the lock housing 10. In the embodiment of the Fig.2 the blocking element 12 is designed as a blocking slide 13. Furthermore, the electronic additional module 2 is arranged in the lock housing 10, which has the electronic module blocking element 20. The electronic module blocking element 20 is in the embodiment of the Fig.2 designed as an electronic module blocking slide 23.

In the example of Fig.2 Two blocking slide rollers 14 are arranged on the blocking slide 13 so that they can rotate. Two electronic module blocking slide rollers 24 are also arranged on the electronic module blocking slide 23 so that they can rotate. The bearing axes of the two blocking slide rollers 14 and the two electronic module blocking slide rollers 24 are parallel to one another, with the two blocking slide rollers 14 of the blocking slide 13 or the two electronic module blocking slide rollers 24 of the electronic module blocking slide 23 contacting one another, as shown in Fig.2 shown.

In Fig.2 the blocking element 12 is arranged in the blocking position in which the blocking slide 13 with the blocking slide rollers 14 of the blocking element 12 engages behind the lock latch 11 and a movement of the lock latch 11 is blocked. Furthermore, in Fig.2 the electronic module blocking element 20 is arranged in the blocking position in which the electronic module blocking slide 23 with the electronic module blocking slide rollers 24 of the electronic module blocking element 20 engages behind the lock latch 11 and a movement of the lock latch 11 is blocked.

In the blocking position of the blocking element 12 in Fig.2 the blocking slide 13 of the blocking element 12 engages behind the lock latch 11 in such a way that one of the two blocking slide rollers 14 rests against the rear edge of the lock latch 11, with the blocking slide rollers 14 assuming a dead center position in relation to the rear edge of the lock latch 11. This is possible because the directions of movement of the lock latch 11 and the blocking element 12 are perpendicular to one another. The lock latch 11 cannot therefore be moved by an external force acting on the lock latch 11, since the force is introduced into the two blocking slide rollers 14 in the dead center position.

This applies equally to the electronic module blocking element 20 in Fig.2 . In the blocking position of the electronic module blocking element 20 in Fig.2 the electronic module blocking slider 23 of the electronic module blocking element 20 engages behind the lock latch 11 in such a way that one of the two electronic module blocking slider rollers 24 rests on the rear edge of the lock latch 11, with the electronic module blocking slider rollers 24 assuming a dead center position in relation to the rear edge of the lock latch 11. This is possible because the directions of movement of the lock latch 11 and the electronic module blocking element 20 are perpendicular to one another. The lock latch 11 cannot therefore be moved by an external force acting on the lock latch 11, since the force is introduced into the two electronic module blocking slider rollers 24 which are in the dead center position.

Fig. 3 shows the lock 1 according to the invention with additional electronic module 2 from Fig.2 , whereby in the Fig. 3 the blocking element 12 is in the release position and the electronic module blocking element 20 is in the release position. When both the blocking element 12 and the electronic module blocking element 20 are in the release position, the lock latch 11 is pivotable and translationally displaceable, ie the lock latch 11 can be pushed into the lock housing 10.

In this embodiment, the blocking element 12 is moved into the release position by the lock mechanism. In this embodiment, the electronic module blocking element 20 is moved into the release position by a drive of the additional electronic module 2.

In the release position of the blocking element 12, the blocking slide rollers 14 on the blocking slide 13 do not engage behind the lock latch 11, as in Fig. 3 shown by the blocking slide rollers 14 in the embodiment of the Fig. 3 by the blocking slide 13 out of the area of the rear edge of the lock latch 11. A shift of the two blocking slide rollers 14 out of the dead center position causes a safe release of the lock latch 11.

This applies in the same way to the electronic module blocking element 20. In the release position of the electronic module blocking element 20, the electronic module blocking slide rollers 24 on the electronic module blocking slide 23 do not engage behind the lock latch 11, as in Fig. 3 shown by the electronic module blocking slide rollers 24 in the embodiment of the Fig. 3 by the electronic module blocking slider 23 out of the area of the rear edge of the lock latch 11. A shift of the two electronic module blocking slider rollers 24 out of the dead center position causes a safe release of the lock latch 11.

Fig.4 shows the lock 1 according to the invention with additional electronic module 2 from the Fig. 2 and 3 , whereby in the Fig.4 the blocking element 12 is in the blocking position and the electronic module blocking element 20 is in the release position.

Fig.5 shows the lock 1 according to the invention with additional electronic module 2 from Fig. 2 to 4 , whereby in the Fig.5 the blocking element 12 in the release position and the electronic module blocking element 20 is in the blocking position.

The lock latch 11 can be blocked either only by the blocking element 12 ( Fig.4 ), or only by the electronic module blocking element 20 ( Fig.5 ) or simultaneously by the blocking element 12 and the electronic module blocking element 20 ( Fig. 3 ) can be carried out. A release of the lock latch 11 in the embodiment of the Fig. 2 to 5 occurs when both blocking elements, i.e. the blocking element 12 and the electronic module blocking element 20, release the lock latch 11.

Fig.6 shows a second embodiment of the lock 1 according to the invention with an additional electronic module 2, in which the additional electronic module 2 prevents or allows a transmission of the movement of the lock mechanism to the blocking element 12 by means of a switchable electronic module displacement element 25.

The Castle 1 in Fig.6 has a lock housing 10 with a lock mechanism arranged therein and the lockable lock latch 11. The lock latch 11 is designed in this embodiment as a tilt latch 17 which is pivotably arranged on a latch carrier 15. The latch carrier 15 of the tilt latch 17 is mounted in the lock housing 10 so as to be linearly movable. The direction of movement of the latch carrier 15 is horizontal in the installed position of the lock 1, with the direction of movement of the latch carrier 15 and the tilt latch 17 mounted thereon being parallel to the direction of movement of a Fig.6 not shown locking element. The pivot axis of the tilt latch 17 runs parallel to the extension axis of a faceplate of the lock 1 and perpendicular to the direction of movement of the latch carrier 15. The latch carrier 15 is acted upon by a spring 16 supported on the lock housing 10, which urges the latch carrier 15 in the direction of its extended position, as shown in Fig.6 shown.

A blocking element 12 which can be moved by the lock mechanism is arranged in the lock housing 10. In the embodiment of the Fig.6 the blocking element 12 is designed as a blocking slide 13. In the embodiment of the Fig.6 Two blocking slide rollers 14 are rotatably mounted on the blocking slide 13. The bearing axes of the two blocking slide rollers 14 are parallel to each other, whereby the two blocking slide rollers 14 of the blocking slide 13 contact each other, as shown in Fig.6 shown.

Furthermore, the electronic additional module 2 is arranged in the lock housing 10, which has the electronic module displacement element 25. The electronic module displacement element 25 is in the embodiment of the Fig.6 designed as a displaceable arm, which engages with its free end on the blocking slide 13 of the blocking element 12. In the embodiment of the Fig.6 the additional electronic module 2 is arranged on a movable part of the lock mechanism and transmits or prevents the movement of the lock mechanism via the electronic module displacement element 25 to the blocking slide 13 of the blocking element 12.

In Fig.6 the blocking element 12 is arranged in the blocking position in which the blocking slide 13 with the blocking slide rollers 14 of the blocking element 12 engages behind the lock latch 11 and a movement of the lock latch 11 is blocked. It is essential that in Fig.6 the movement of the lock mechanism (arrow in Fig.6 ) by the additional electronic module 2 by means of the coupling of the electronic module displacement element 25 with the blocking slide 13, ie the movement of the lock mechanism is transmitted to the blocking slide 13 by the electronic module displacement element 25.

In the blocking position of the blocking element 12 in Fig.6 the blocking slide 13 of the blocking element 12 engages behind the lock latch 11 in such a way that one of the two blocking slide rollers 14 on the rear edge of the lock latch 11 , whereby the blocking slide rollers 14 assume a dead center position in relation to the rear edge of the lock latch 11. This is possible because the directions of movement of the lock latch 11 and the blocking element 12 are perpendicular to one another. The lock latch 11 cannot therefore be moved by an external force acting on the lock latch 11, since the force is introduced into the two blocking slide rollers 14 which are in the dead center position.

Fig.7 shows the lock 1 according to the invention with additional electronic module 2 from Fig.6 , whereby in the Fig.7 the blocking element 12 is in the release position. It is important that in Fig.7 the movement of the lock mechanism (arrow in Fig.7 ) for moving the blocking element 12 into the release position by the additional electronic module 2 through the coupling of the electronic module moving element 25 with the blocking slide 13, ie transmits the movement.

When the blocking element 12 is in the release position, in which the electronic module blocking element 20 allows the movement of the lock mechanism, the lock latch 11 can be inserted into the lock housing 10. In the release position of the blocking element 12, the blocking slide rollers 14 on the blocking slide 13 do not engage behind the lock latch 11, as shown in Fig.7 shown by the blocking slide rollers 14 in the embodiment of the Fig. 3 by the blocking slide 13 out of the area of the rear edge of the lock latch 11. A shift of the two blocking slide rollers 14 out of the dead center position causes a safe release of the lock latch 11.

Fig.8 shows the lock 1 according to the invention with additional electronic module 2 from Fig. 6 and 7 , whereby in the Fig.8 the blocking element 12 is in the blocking position, in that the electronic additional module 2 prevents the transmission of the movement of the lock mechanism to the blocking element 12 by the displacement of the electronic module displacement element 25, ie the movement of the lock mechanism is not transmitted. To this end, the

Electronic module displacement element 25 controls the movement of the lock mechanism by pushing the electronic module displacement element 25, which is designed as an arm, further out of the housing of the electronic module displacement element 25. This can be done by a drive of the additional electronic module 2, or by the electronic module displacement element 25 being arranged in a freely movable manner in the additional electronic module 2 in this case.

In this embodiment, the lock latch 11 can be blocked either by allowing the movement of the lock mechanism onto the blocking element 12 ( Fig.6 ) or preventing the movement of the lock mechanism onto the blocking element 12 by the electronic module blocking element 20 ( Fig.8 ) is carried out. A release of the lock latch 11 ( Fig.7 ) is carried out by allowing the movement of the lock mechanism onto the blocking element 12 for release by the electronic module blocking element 20.
